The window of opportunity to turn back abortion, gay rights, sexual liberation was in the 80s. Reagan was president and he had the opportunity to appoint 3 Supreme Court justices. He appointed one conservative, and two pro-Roe liberals. That was it, that did it. It was over at that point.
Abortion has been legal for decades now, and it's considered a basic right by the large and growing population of single women in America. They consider abortion rights a fundamental element of their personal dignity and they're never going to give it up. Despite the polls continuing to show conflicted public opinions on abortion, voters (even in very conservative states like MS and SD) reliably reject even the most modest abortion restrictions at the ballot box.
Similarly, support for gay rights has taken off like a rocket ship in recent years. It's now a virtual consensus among young people that gays should have every protection other minorities have, should have the right to marry, etc. I've personally been astonished how fast liberals have routed conservatives on gay issues, and their charge is not letting up.
So, like it or not, the culture war is over. You can continue to preach in your churches, if you'd like. You can continue to picket clinics, you can continue to try to persuade. However, if you continue to demand that the GOP carry your water against the "sickos" or whatever, you're just helping to further cripple the party in future elections.
